Dynamics and Equilibria of N Point Charges on a 2D Ellipse or a 3D Ellipsoid
… Thomson problem which refers to finding the equilibrium distribution of a finite number of mutually repelling point charges on the surface of a sphere, but for the case where the sphere is replaced by a spheroid or ellipsoid. To get started, we first consider the problem in two dimensions, …

The Computer Simulation of Dilute Solution Particle Dynamics
… models in dilute solution is described. Equilibrium, shear and extensional flow fields are considered. The program tracks particles individually and is therefore capable of calculating statistical averages of a wide range of properties; particle inertia and Brownian motion are included in …

Market Policies for Control of Multiple Pollutants: Management Issues and Methods of Analysis
… are grouped together, and (3) determining the equilibrium distribution of financial burden among dischargers participating in TDP markets for multiple pollutants. These approaches are demonstrated for a water quality management program that controls BOD, phosphorus, and nitrogen discharges in a …

Self-organized fine-tuned response in a driven spin glass
… energy decreasing as compared to the near-equilibrium distribution. Which spins fall into which categories is specific to a particular realization of the external drive; changing to another drive changes which spins are fast and which are slow, revealing a drive-specific adaptation. I …

Modeling the diffusion of reactive and nonreactive solutes in cores from the Cannikin Test Site, Amchitka Island, Alaska
The migration and distribution of contaminants in the subsurface environment are controlled by groundwater movement and the extent of interaction between the contaminants and surrounding rock matrix. Studies have shown that diffusion through the rock matrix may serve as a prominent contaminant …

Maximum entropy quadratic model to characterize chemical non-equilibrium in re-entry flows
This thesis presents the study of an advanced non-equilibrium model for state-specific chemical kinetics based on method of moments. The focus of this project is on the rovibrational chemical kinetics of the N2-N system. Internal excitation, dissociation, recombination and energy transfer …

Folding-Driven, Nucleation -Elongation Polymerization of Phenylene Ethynylene Imines
… with the monomer in excess. Thermodynamic equilibrium was established by showing that the same distribution was reached starting either from a monomer mixture or from high polymer to which one monomer was added. These results are in great contrast to the low molecular weight oligomers …

Generalized Markov branching models
… In addition, an explicit expression for the equilibrium distribution is presented. We then moved on to investigate the basic properties of an extended Markov branching model, the weighted Markov branching process. The regularity and uniqueness criteria of such general structures are first …

Mesoscopic lattice Boltzmann nemato-dynamics.
… LBE schemes, the standard momentum density distribution and a new link angle distribution. To achieve evolution, the link angle distribution undergoes a Bhatnagar-Gross-Krook (BGK) collision step and advects (propagates) in unit time with the momentum densities. Anisotropy is introduced into …

Methanol amination over hydrothermally treated zeolites RHO and Modernite
… yields a thermodynamically controlled product distribution. The equilibrium distribution for mono-, di-, and trimethylamine (MMA, DMA, and TMA), at 325°C and a molar methanol to ammonia ratio of 1, is 17, 21, and 62 mol % respectively. The market demand, on the other hand, is for about 33, 53, …

Thermal equilibrium theory of periodically focused charged-particle beams
A thermal equilibrium theory of periodically focused charged-particle beams is presented in the framework of both warm-fluid and kinetic descriptions. In particular, the thermal beam equilibria are discussed for paraxial beams in periodic solenoidal and quadrupole magnetic focusing fields, and the …

Inequality Under Frictional Labour Markets
… frictions and human-capital accumulation for the equilibrium distribution of wages when firms invest optimally in match-specific productivity. Optimal investment choice is incorporated in a framework along the lines of (Burdett et al., 2011) and equilibrium is characterised. The effect of the rate …

Countercurrent chromatography of proteins using aqueous two-phase systems
… proteins did not elute as predicted from their equilibrium distribution ratios. It appears that the wave - like mixing and settling behaviour of the phases in the centrifuge was insufficient for the proteins to achieve equilibrium partitioning. A centrifugal partition chromatography (CPC) …

Analysis of rubber vulcanisates
… in the casing than in the sidewall. An equilibrium distribution is not obtained. After 114 days at 50oC in 95% relative humidity, the level of solvent extractable 6PPD fell to zero, but subsequent ageing for 2 years in 50 pphm ozone showed no evidence of sidewall cracking. It is …

Multicellular self-assembly on patterned surfaces
Controlling the spatial distribution of cells in two and three dimensions may be important in the design of advanced tissue engineering scaffolds and other biomedical applications. In this thesis, the concept of biophysical sorting was applied as a method to control the spatial distribution of …

Sorption and Biodegradation of Organic Solutes Undergoing Transport in Laboratory-scale and Field-scale Heterogeneous Porous Media.
… the magnitude of the organic carbon normalized equilibrium distribution coefficients. The sorbates sorbed more strongly to the humic-coated soil, most likely due to the organic matter's less polar nature as compared to the fulvic material. The molecular solute descriptor, ¹Xᵛ, performed slightly …

Causal Programming
